Abstract

L'invention concerne la synthèse d'une silice précipitée présentant des propriétés chimiques et physiques améliorées, convenant en tant que charge renforçante de matrices polymères. Ces propriétés améliorées sont obtenues au moyen d'une synthèse de silice effectuée avec une force ionique réduite. L'utilisation d'acide silicique pendant la synthèse permet en particulier d'obtenir une solution présentant un force ionique réduite qui favorise la formation d'une structure colloïdale améliorée par une augmentation de l'agrégation et une diminution de l'agglomération. De plus, la surface du précipité de silice ainsi formé peut être modifiée par l'adjonction d'agents modificateurs de surface au cours de la synthèse afin d'améliorer encore les propriétés de renforcement désirées de la silice précipitée. L'invention concerne également des compositions polymères présentant une résistance à la traction et une résistance à l'allongement améliorées. Ces compositions contiennent une silice précipitée synthétisée avec des forces ioniques réduites présentant des surfaces modifiées, combinée à un composé polymère.
